What I miss in the CLI, is proper structure in the text.
For example, a good IDE will list all problems found with your code, ordered in a sensible way. If I then click in a problem, it expands, and I get to see the full text description of that error. I can then click on a file/line combo, and be directed immediately there.
If I run CMake directly, I get kilobytes of error message dumped into a single blob of text.
Colors, line prefixes, and separator lines attempt to bring some structure into this mess, but it still remains a big wall of text.
It takes less effort for me to process the data presented to me by a good IDE, because it is organized and structured.
Same thing with git commits/branches/tags.
Same thing with diffs/merges.
Almost ALL text data can be organized in some way. But most text data is not big enough or common enough, that it is worth our time and effort to structure it that well. I therefor see GUIs as tools for when you are doing something so commonly done, that the effort of structuring the data was worth it.
